Just installed, seems to be working fine
I have a slow leak based on my increased water bill. So I installed this meter right outside my house. This has allowed me to determine that the leak is most likely past my shutoff, and unfortunately probably under my slab. (I can see that the leak is not in my yard between the water company meter and the side of the house). Positives: - Fairly easy to install. I had to dig out a hole to put it in, and also installed an in ground meter box. (note: I had a nice straight run of pipe to put it in, which is required to have accurate measurements) - No additional power wiring required on the outside of the house - The digital part that goes on the outside of the house uses standard AA size batteries (requires lithium AA batteries but comes with them). - The part that goes inside the house uses a standard USB plug and includes both WIFI and Ethernet port. I did initial setup with Ethernet and then was able to put the WIFI on my guest network (did not require local LAN access). Works fine with the Ethernet cord unplugged. - Both the Yolink hub and the outside digital part of the meter paired easily with the Yolink app (Android phone, app is in the play store). Paring is done by scanning a QR code, first on the Hub. And then later scanning the QR code on the back of the digital part of the meter. - Customer service responded very quickly to my feedback about the app. Negatives: - You only get a total water used amount and not a flow rate, where the water company meter gives GPM (you can select the units between Gal, L, CCF, M3). - My leak is too slow to be continuously monitored by the digital part. If I am not using water, my leak shows up as a periodic blip once an hour of about 5 gal. The meter is still measuring the amount, it just doesn't get reported on the app constantly. This is also kind of a feature because it helps preserve the battery life. - The wiring between the flow meter and the digital part that stays outside could be better. It comes with generic WAGO type connectors to connect between the digital part and the meter. There is no enclosure for this connector and it is left exposed. I kind of want to get an external box to put the digital part in now even though it is IP66 rated. - The app is not very intuitive. It does have quite a few features (it is designed to work with other yolink devices, but I only have the water meter). I was hoping to share the device with another user. I initially didn't see any option to do this in the app. So I submitted feedback that the functionality should be added. Yolink responded with instructions on how to set it up, since the feature was already there.

Easy access to the data.
I works perfectly. One of my DYI project for my home. I bought it because I have problem with the Septic System and the builder says that the RO filter under the kitchen sink is causing the problem. I have well and one of the option was to put a water meter to measure the incoming water to the house. I look all the data from my telephone app and printed all the data needed to fight the problem. I recommend it.

Easy to install, accurate readings
Easy to install, accurate water meter. Works well with the yolink YS 5007 to provide accurate water consumption data

YoLink does the job
Had my well service guy install inline with my main house water line. Works great and the historical data views are really helpful. The WiFi adapter has great range, reaching my WAP from the pump house about 100’ away. Would recommend.

Easy to install and set up
I bought the 1" version as that was my supply pipe size. It comes with a union type connector in the flow meter and a 1" MNPT connection at the other. I used shark bite fittings and PEX tubing to compete the install. Appears to be accurate compared to what I think certain things should use and my test filling a 5 gallon bucket. I have the SS version and its pretty heavy. Going to need to install a support to take the stress off the piping. Set up was easy and had it working in less than 15 minutes including setting up the account and installing the app

It all works
Monitors a restroom building and have already detected sinks running 4 times. Signal does reach indoor hub fine and the app seems great. Bought a second hub for kitchen with water sensors on floors and a motion detector. Happy customer here.

Great for checking water usage remotely
I had a water leak between my meter and my home and didn't realize it until the next water bill showed up. Now I have this meter right next to the city meter and I can check the water usage anytime from anywhere. I love how far the signal travels! So much stronger than regular WIFI. Like 10x stronger. Easy to install and set up. The only downside with the app is that I cannot see the gallons used over a specific period. I can see the a chart of hourly or daily usage. And I can see a chart of an entire month, but it doesn't show the number of gallons over that period of time. I need to download the data, put it in Excel and get the total there. I can see the meter reading at any point, so if I were to write down the reading on the first of every month, I could calculate it easily. I just wish the total number was clearly displayed on the screen. It's also not clear if it sends the leak notifications automatically, or if there is something that needs configuring. But for me the most important thing is that I can see the number anytime (and also double check the city meter reading!)
